Find the area of the figure. Explain your reasoning.

Answers

Answer:

Separate it into smaller figures.

Step-by-step explanation:

The figure can be separated into a triangle on the top, and 2 trapezoids on the middle and the bottom.

The area of the triangle is bh/2, which is (4 x 6)/2, which is 12.

The area of the trapezoid in the middle is .5(b1+b2)h, which is .5(6+4)3, which is 15.

The area of the trapezoid on the bottom is .5(6+5)2, which is 11.

Now, add them to get 12+11+15 which is 38.

Answer: Not sure I have this problem too and i’m trying to figure it out.

Step-by-step explanation:

It’s not 38. There is another two other triangles and a rectangle, along with a square. The triangles formula is a=bxh/2 and the parallelogram or rectangles formula is bxh.

Once your done, you add all them together.

The two other triangles are in the middle in the little corner, and the other one in the bottom left corner.

Answers

I think the correct answer would be C, it might be A but I’m pretty sure its C. If you google a graph and Mark all the coordinates you’re given and connect the dots you will be given a shape. A parallel a gram would be something like a square, rectangle, etc hence the word “PARALLEL” meaning the opposite angle is straight, the same length, and going in the same direction as the one opposite to it. The dots on the graph do not make a parallelogram this concluding the answer is “ no “ leaving it to be A or C and I believe it would be C because the lines opposite of it do not have the same length

It takes about 20 minutes to grade a student’s paper. How long, in hours, does it take to grade papers for a class of 30 people?

Answers

Answer:

it would take around 10 hours to grade all 30 papers

Step-by-step explanation:

if for one student it takes 20 minutes that means you would have to do 20 minutes 30 times which is 600 minutes. to convert that to hours you divide total minutes (600) by 60 which gives you 10 hours. no need for thanks

Pls solve with steps

Answers

A. X+3=2x so x=3 because 2x-x is equal to x.
B. 5=2x so 5/2 =x.
C. 2x+1=3 subtract the 1 over which will equal 2x=2 so x=1
D. On this one you have to have the same first number and it would be easier to make it 2^3(70) which is 210=x.
